FLASHING FOR BOOFS OR THE LIKE.

Application filed January 24, 1927. Serial No. 163,052.

. I v My present invention relates in general --to roofs and the likeweatherproof coverings, and has particular reference to a so-calledflashing for sealing and anchoring the end -of root coverings andgutters at their juncture with walls, chimneys and other terminals orobstructions.

- chimneys and the like locations.

Various ex pedients have been carried out to eflect a weatherproofseal'ztor the roof covering, some of which, while eifective for allpractical purposes, require considerable effort to build. Othersmoreeasily made are not always as eflective as they should be,-

and very often unsightly.

lVith my invention I can prod ce not only a positive seal, so to speak,but one which will be'unusually neat in appearance, easy to install andcheap to produce.

In the accompanying drawing, which illustr'ates several embodiments ofthe invention Figure 1 is a perspective View of a portion of awall'showing a roof covering adjacent thereto, and illustrating theapplication of the invention.

Figure 2 is a perspective view in detail of one part of the flashingstrip.

Figure 3 is a perspective view in detail of a companion part of theflashing strip.

Figure 4 is a view in cross-section showing one way of anchoring theroof covering in the flashing strip.

Figure 5 is a similar view showing a slightly modified way of anchoringor securing the roof covering in a flashing strip; and v Figure 6 is aview in cross-section showing a similar modified form of flashing strip.Referring now to the drawing in detail. For the purpose of illustrationI have shown a brick wall 5, 6 representing a roof'witha flexiblecovering 7 therefor. The difliculty heretofore experienced has' b'een tomake some kind of a positive seal for the termination of the covering 7,so as to realize a .completely sealed waterproof covering. for

the root. v

According to my invention I propose to usepractically a two-partflashing strip,

consisting of a base section 8 and ,a .cover section 9. In Figure 3these parts and 9 can u sually be made inelongated strips of 2.

ends adapted to abut one another so that several of the sections'may beused to develop a flashlng-strip along the side of a relatively longwall.,or the like. As shown -in Figure l the flashing strip is installedas length suitable for the purpose, with their an insert, so to speak,in a brick structure.

For thispurpose it would be desirable to make the depth ofthe base 8equal to that of the depth or thickness of an ordinary build ing brick.The width of the flashing when the cover 9 is applied to the base 8should be equal'to that of half of a brick, so that the flashingmay beinstalled in the brick structure without special arrangements. In otherwords it would simply take the place of the bricks for the length of thewall re quired for the flashing.

The base 8 iscmade with a modified rabbeted or mortisededge, made toaccommodate the cover 9, so that the concave underside. 10 of the cover9will fit over the convex surface 11 of the base, and with the verticalside 12 of the cover fitting against the vertieal edge 13 of the base.This makes up a mortised joint. flashing strip may be conveniently andcheaply made from an extruded, flbrated asphalt composition. In otherwords, the strip is. made up of sections 8 and 9. The sectionswhenjoined should have some qualities of compressibility, although'rigidand strong enough to. enter into the wall construction withoutinterferingv with the supporting-qualities of the brick work. Ipreferably' make the flashing strip. of fibrated asphalt composition inorder to obtain compressibility and waterproofing qualities of theflashing, and also for cheapness and con: venience in manufacture.

r In installingthe flashing the brick workwill be carriedon up to wherethe flashing is to be installed, then the 'base 8 may be inserted in itsproper 'position and the brick work carriedon as required. When the timecomes to lay. the roof covering 7 the I edge of the same may be laidover the base of the flashing, and the cover?) then inserted andhammered, or otherwise forced into place.

in Figure 4. This impaling means will pass As shown in Figure '5 I mayuse a layer These two parts of the- To securely anchor the end oi thecovering in the flashing, .nails or other impaling means 14 may beemployed as shown I v adapted to enter into engagement with one orcoating of mastic, or the like, on opposite sides of the inserted edgeof the covering to effect a more positive seal if desired.

The impaling'fneans 14 may or may not be used in this combinati0n.' l

In Figure 6 I have shown dove-tailed slots'16 in the. underside and topof the base 8, and in thetop of the cover 9. The

purpose of these slots is to interlock with the plaster or mortar of thebrick work .so'

as to hold the flashing .strip in. place? If usin a cover 9 with slot 16therein it would 'not. 'e altogether practical to insert the cover .9after the brick work had been car-. -15

ried beyond the flashing strip: For. this a reason it would be moredesirable in using this form to terminate the'brick work at the flashingand install and lock the flashing, in place before carrying the brickwork, on. i

As will be seen from Figure 1 I am enabled to. develop an exceedinglyneat and practical flashing, and particularly one which makes a mosteif'ec tive weatherproof seal betweenthe roof covering and the wall, orother surfaces presented at right angles thereto. The flashing is easyto install, easy and cheap to make and, as stated; unusually effective.i a
